Trump supporters, Protesters clash after Chicago rally postponed

Chicago (CNN) – Donald Trump’s campaign on Friday postponed a rally in Chicago amid fights between supporters and demonstrators, protests in the streets and concerns that the environment at the event was no longer safe.

The announcement, which came amid large protests both inside and outside the event at the University of Illinois at Chicago, follows heightened concerns about violence in general at the GOP front-runner’s rallies. Illinois holds its Republican primary on Tuesday.

Hundreds of demonstrators packed into an arena, breaking out into protest even before Trump had shown up. At least five sections in the arena were filled with protesters.
